COMBINED PIPE-WRENCH AND PLIERS.

SPECIFICATION forming part of LettersPatent No. 787,523, dated April 18, 1905. Application filed March 22, 1904. Serial No. 199,358.

To all whom it may concern.-

Be it known that I, GILBERT M. MAsoN, a citizen of the United States, residing at Cambridge, in the county of Story and State of Iowa, haveinvented certain new and useful Improvements in a Combined Pipe Wrench and Pliers, of which the following is a specification.

The object of my invention is to provide a tool of simple, durable, and inexpensive construction that may be readily, quickly, and easily adapted for use either as a pipe-wrench or as a pair of pincers.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a side elevation of the tool, part of the sliding handle member broken away to show certain details of construction. The dotted lines therein show the adjustable handle member at its inner limit of movement. Fig. 2 shows a side elevation of the opposite side of the wrench with the movable handle member in the position required for use as a pipe-wrench. Fig. 3 shows an edge View of the tool with the fixed handle member uppermost. Fig. 4 shows a side view of a modified form of the device with the handles broken away. The dotted lines indicate an adjusted position of the movable handle member. Fig.-

5 shows a detail perspective View of the adjustable handle member of the modified form, and Fig. 6 shows asectional view through the line 6 6 of Fig. 4.

Referring to the accompanying drawings, I

have used the reference-numeral 10 to indi-.

cate the body portion of one of the jaw members having a straight-edged jaw 11 and an integral handle member 12. The numeral 13 indicates the body portion of the other jaw member having an integral jaw 14, provided with a toothed concave surface 15 to adapt the device for use as a pipe-Wrench. The numeral 16 indicates a handle member adjustably secured to thebody portion of the jaw member 13. The said jaw members are pivotally connected by means of a rivet 17 in the ordinary way. The rear edge of the jaw member 13 is segmental in shape and is provided with a series of notches 18 and arearwardly-projecting lug 19. It is also provided with a slot 20, the body portion of which is of segmental form concentric with the pivot-pin 17, and one part of the slot 20 is curved inwardly toward the pivot-pin and terminates with an outwardlyprojecting portion extended in a direction toward the projection 19. The movable handle member 16 is provided withlugs 21, overlapping the sides of the jaw member 13, and a pin 22 is passed through said lugs and through the slot 20. Said handle member is also provided with a socket 23 to receive the projection 19. These parts are so arranged that when the handle member 16 is in the position shown in Fig. 2 it .is simply pivotally connected with the jaw member 13, and it forms with the handle member 12 a handle that may be easily grasped.

Assuming that it is desired to connect the handle member 16 with the jaw member 13 in a rigid manner, then the operator moves the handle member so that the pin 22 traverses the slot 20 until it reaches the end of the slot adjacent to the projection 19. Then the handle member 16 is moved inwardly toward the jaw member 13 until the projection 19 enters the socket 23. formed in the handle member 16, as shown in Fig. 1, and when in this position the, handle member 16 is rigidly connected to the jaw member 13 and can only be released from its position by first moving the handle member 16 toward the pivot-pin 17 until the pin 22 is moved to the concentric portion of the slot 20,, whereupon the projection 19 disengages from the socket 23, and the handle member 16 then becomes pivotally and slidingly connected with the jaw member 13. I have also provided means by which the handle member 12 may be rigidly secured to the jaw member 13, as follows: Formed in the handle member 12 is a slot 24. A sliding sleeve 25 is passed through said slot 24 and around the adjacent portion of the handle 12 and is provided with a projection 26, capable of entering the notches 18 of the jaw member 13. W'hen the sleeve 25 is at its outer limit of movement, the jaw member 13 may move freely relative to the handle 12; but when the sleeve 25 is at its inner limit of movement its projection 26 enters one of the notches 18 and locks the adjacent members and 13 together.

In practical use and assuming that it is desired to use the tool as a pair of pincers the handle member 16 is placed in position with the projection 19 in the socket 23, and the sleeve 25 is moved to its outer limit, as shown in Fig. 1. In this way each jaw member has a handle member rigidly secured thereto, and as the outer ends of the jaws are substantially parallel with each other when closed the tool may be used for all the purposes for which an ordinary pair of pincers are used. If desired, the outer ends of these jaws may be formed with teeth, as shown in the drawings, for the purpose of more firmly securing objects between the jaws. When the device is intended for use as a pipe-wrench, it is necessary that the jaws be set and secured at a certain distance relative to each other, far enough apart to admit a pipe or rod between theconcave portion of one jaw and the adjacent portion of the other. I therefore place the pipe or rod to be turned between the jaws and then set the collar so that its projection 26 enters the adjacent notch 18. In this way the jaws are arranged to stand close to the opposite sides of the pipe or rod to be turned, and the said jaws are rigidly held in this position. I then move the handle member 16 to position with its pin 22 in the concentric portion of the slot 20, so that the operator may easily grasp botli of the handle members and use them as a single handle that is rigidly secured to both the jaw members. and in this way the pipe or rod may be turned in the same manner as with the ordinary pipewrench.

In the modified form shown in Figs. 4: and. 5 I have illustrated an adjustable handle member 27, having two lugs 28 on one end to overlap the sides of the jaw member 13 and the cross-piece 29, connecting them, and I have also formed in the projecting portion of the jaw member 13 a notch to receive the said cross-piece 29. The other parts of this handle are the same as in my preferred form, and in operation the cross-piece 29 enters the notch 30 and produces the same result, as to rigidly securing the handle member to the jaw member, as in my preferred form when the projection 19 enters the socket 23. In this modification I have also shown a set of ratchetteeth 31, formed on the periphery of the jaw member 13, instead of the notches 18 of my preferred form, and on the sliding collar 25 I have formed an extension 32, provided with ratchet-teeth designed to engage the In other respects the modiratchet-teeth 31.

l fied form corresponds exactly with the pret'erred form, and I have used the same reference-numerals in both forms to apply to corresponding parts.

When the jaws are in their position for use as a pipe-wrenchthat is, are fixed in position relative to each otherthe outer ends of the jaws may be used for turning nuts and angular objects of various sizes in the same manner as the ordinary alligator-wrench is used.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. The combination of two jaws pivotally connected, a fixed handle on one jaw, a pivoted handle on the other jaw and means for securing the fixed handle to the jaw having a pivoted handle.

- 2. The combination of two members pivotally connected, each comprising a jaw and a handle, one of the handles fixed to its jaw and the other handle pivoted to its jaw and means for adjustably securing the fixed handle to the jaw having the pivoted handle.

3. The combination of two members pivotally connected, each comprising a jaw and a handle, one of the handles fixed to its jaw and the other handle pivoted to its jaw and means for rigidly securing the pivoted handle to its 1. The combination of two members pivotally connected, each comprising a jaw and a handle, one of the handles fixed to its jaw and the other handle pivoted to its jaw, means for rigidly securing the pivoted handle to its jaw and means for securing the fixed handle to the jaw of the pivoted handle.

5. The combination of two jaw members pivoted together, a handle rigidly secured to one jaw member, means for adjustably connecting the said handle with the opposite jaw member, a second handle pivoted to the remaining jaw member and means for rigidly securing the latter handle to its jaw member.
